      drm: Simplify stacktrace handling · 487f3c7f
      Thomas Gleixner authored
      Replace the indirection through struct stack_trace by using the storage
      array based interfaces.
      
      The original code in all printing functions is really wrong. It allocates a
      storage array on stack which is unused because depot_fetch_stack() does not
      store anything in it. It overwrites the entries pointer in the stack_trace
      struct so it points to the depot storage.

      Replace the indirection through struct stack_trace by using the storage
      array based interfaces.
      
      The original code in all printing functions is really wrong. It allocates a
      storage array on stack which is unused because depot_fetch_stack() does not
      store anything in it. It overwrites the entries pointer in the stack_trace
      struct so it points to the depot storage.

      lib/stackdepot: Provide functions which operate on plain storage arrays · c0cfc337
      Thomas Gleixner authored
      The struct stack_trace indirection in the stack depot functions is a truly
      pointless excercise which requires horrible code at the callsites.
      
      Provide interfaces based on plain storage arrays.

      stacktrace: Provide helpers for common stack trace operations · e9b98e16
      Thomas Gleixner authored
      All operations with stack traces are based on struct stack_trace. That's a
      horrible construct as the struct is a kitchen sink for input and
      output. Quite some usage sites embed it into their own data structures
      which creates weird indirections.
      
      There is absolutely no point in doing so. For all use cases a storage array
      and the number of valid stack trace entries in the array is sufficient.
      
      Provide helper functions which avoid the struct stack_trace indirection so
      the usage sites can be cleaned up.

      tracing: Cleanup stack trace code · 3d9a8072
      Thomas Gleixner authored
      - Remove the extra array member of stack_dump_trace[] along with the
        ARRAY_SIZE - 1 initialization for struct stack_trace :: max_entries.
      
        Both are historical leftovers of no value. The stack tracer never exceeds
        the array and there is no extra storage requirement either.
      
      - Make variables which are only used in trace_stack.c static.
      
      - Simplify the enable/disable logic.
      
      - Rename stack_trace_print() as it's using the stack_trace_ namespace. Free
        the name up for stack trace related functions.
